Millimeter-Wave Backscatter Measurements in Support of Surface NavigationApplications

摘要

Millimeter wave (MMW) short range radar systems have unique advantages in surfacenavigation applications, such as military vehicle mobility in inclement conditions, aircraft landing assistance and missile guidance. Two types of radar cross section (RCS) measurements were performed at 95 GHz. Grazing angle clutter data were obtained from common surfaces. The RCS of objects, commonly encountered by automobiles on the road, was also measured. In addition the received power statistics were investigated for both types of RCS measurements. The average normalized RCS values are presented for each surface. The received clutter power is compared to Rayleigh and Weibull probability distributions. The azimuthal RCS profile was measured and plotted for several roadside objects. These objects included both metal and wood sign posts and a section of guard rail. An average RCS value was also calculated for each object. The received power CDF was compared to the Rayleigh and Weibull distributions.
